Consider this


function Pair(inMin, inMax)
{
    this.min = inMin;
    this.max = inMax;
}

Which would let me use


var somepair = new Pair(5,10);
somepair.min => 5
somepair.max => 10

See this function now


function getTotalScaledScorePair()
{
    var rpair = getReadingScaledScorePair();
    var wpair = getWritingScaledScorePair();
    var mpair = getMathScaledScorePair();
    
    var tmin = rpair.min + wpair.min + mpair.min;
    var tmax = rpair.max + wpair.max + mpair.max;
    return new Pair(tmin, tmax);
}

What I like? Very clear, mostly typed, less likely to make mistakes. Here are some other ways this Pair is used


//SAT.getReadingScaledScorePair = getReadingScaledScorePair;
function getReadingScaledScorePair()
{
    var rawscore = getReadingRawScore();
    var rawscore = Math.ceil(rawscore);
    var vScaledScore =ScaledScoreMap[rawscore];
    return new Pair(vScaledScore.readingMin, vScaledScore.readingMax);
}
//SAT.getWritingScaledScorePair = getWritingScaledScorePair;
function getWritingScaledScorePair()
{
    var rawscore = getWritingRawScore();
    var rawscore = Math.ceil(rawscore);
    var vScaledScore =ScaledScoreMap[rawscore];
    return new Pair(vScaledScore.writingMin, vScaledScore.writingMax);
}
//SAT.getMathScaledScorePair = getMathScaledScorePair;
function getMathScaledScorePair()
{
    var rawscore = getMathRawScore();
    var rawscore = Math.ceil(rawscore);
    var vScaledScore =ScaledScoreMap[rawscore];
    return new Pair(vScaledScore.mathMin, vScaledScore.mathMax);
}

here is how all this is brouht together in html


<div class="aspire_app_sat_form">
<p class="medium">Reading: <strong class="attention medium">
<script>
var rpair = SAT.getReadingScaledScorePair();
document.write(rpair.min);
document.write(" - ");
document.write(rpair.max);
</script>
</strong></p>

<p class="medium">Writing: <strong class="attention medium">
<script>
var rpair = SAT.getWritingScaledScorePair();
document.write(rpair.min);
document.write(" - ");
document.write(rpair.max);
</script>
</strong></p>

<p class="medium">Math: <strong class="attention medium">
<script>
var rpair = SAT.getMathScaledScorePair();
document.write(rpair.min);
document.write(" - ");
document.write(rpair.max);
</script>
</strong></p>

<p class="medium">Total: <strong class="attention medium">
<script>
var rpair = SAT.getTotalScaledScorePair();
document.write(rpair.min);
document.write(" - ");
